There is no solution

Step-by-step explanation:

31/37=m/3

We move all terms to the left:

31/37-(m/3)=0

We add all the numbers together, and all the variables

-(+m/3)+31/37=0

We get rid of parentheses

-m/3+31/37=0

We calculate fractions

There is no solution for this equation

|5x+2|-3 = -3 the absolute value of -3=3

Step-by-step explanation:

There is no solution the answer is 0

m = 7

Step-by-step explanation:

The 3 given angles lie on a straight line, thus sum to 180° , then

8m - 4 + 90 + 5m + 3 = 180, that is

13m + 89 = 180 ( subtract 89 from both sides )

13m = 91 ( divide both sides by 13 )

m = 7
